Help with the Partial Reload

[Noor51]

How would I do a Partial Reload with this script?

For this data there is a new lines that get add to the excel file everyday. The pervious line don't get updated as well.

BO:
LOAD
Product,
"BO Date",
"Open Sales",
"Open Deliveries",
"Unrestricted Stock",
"BO Qty",
"BO ASP",
"BO $"
FROM [lib://Server Qlik Upload Files (Back Order.xlsx]
(ooxml, embedded labels, table is [Back Order Summary]);

@Noor51 Did you tried with Incremental load? Loading new and updated records with incremental load | Qlik Sense on Windows Help or Using QVD files for incremental load | QlikView Help

I can use incremental load, but I want to practice doing particle load since I can't do that successfully yet.
